It looks like gamers won’t have to wait too long for AMD FSR 4 to hit their favorite games, as long as the game already supports FSR 3.1. That’s according to a leaker who suggests that FSR4 should “just work” with previously-supported FSR 3.1 games. It looks like it’s all down to how AMD is able to integrate the support automatically, without developer support.
If this approach works as suggested, AMD will be able to quickly add support for its new and improved AI resolution upscaling technology, supported by the best graphics cards made by the company in a wide range of games. This is good news for gamers, providing a path for graphics upgrades that doesn’t rely on the time and goodwill of busy game developers.
Renowned industry leaker Kepler_L2 made the assertion in a thread on X (formerly Twitter) thread. Speaking with Videocardz, Kepler mentioned that the new driver for RDNA 4 cards, such as the new AMD Radeon RX 9070 XT, includes replacement DLL files that swap out FSR 3.1 for FSR 4.
When asked if this meant that all FSR 3.1 games will support FSR4 on “day one” of launch, Kepler confirmed, saying that “it should just work.” This is somewhat supported by a slide, released by AMD during the FSR 4 announcement at CES, which suggested that the new AI tech upgrade would only be available “for supported games with AMD FSR 3.1 already integrated.” Games that don’t already support FSR will still need developers to add support, however.
By making it much easier to upgrade the quality of FSR, AMD doesn’t need to reinvent the wheel with each new iteration. However, you will need to pick up a new RDNA 4 card, such as the AMD Radeon RX 9070, if you want to use it. If you’re planning on purchasing AMD’s new flagship, the comments by Kepler suggest that FSR 4 support will be available immediately on launch.
During our own FSR 4 hands-on at CES earlier this month, we saw a big difference in quality in the new AI upscaling technology compared to AMD’s earlier efforts, with a sharper image and much less noise. However, the demo didn’t showcase frame generation, so this wasn’t a feature we could test at the time.
It’s hotting up to a more competitive battle for the mid-ground GPU market than expected.
